Modified Graphite Felt Electrode. Application to Electrocatalysis

Abstract

Homogeneously electrooxidized graphite felt electrode was modified by various organo-metallic compounds. The homogeneity of the τ-bonding inside the porous electrode was controlled by cyclic voltammetry and the volume density of attached redox centers was obtained by coulometric measurements. Catalytic properties of such modified electrodes were characterized by cyclic voltammetry and by electrolyses in a flow cell fitted with these electrodes. As an application, styrene oxide was produced from styrene at a graphite felt cathode modified by a manganese (III) porphyrin.
